Thus, the grooves extend longitudinally on both sides of the gasket profile. When installed, the dovetail structure of the gasket profile is held in place by protrusions located in the C-shaped holding rail, also extending longitudinally on both sides along the holding rail. These retaining rails have a minor appearance, especially when the gasket needs to be bent along a sharp curve.

Further, an opening in a body of an automobile, for example, a window,
Some embodiments of a fixing element for fixing a removable gasket profile in an opening of a door, a sunroof or a rear hatch are described in DE 198 08 044 A1.
It is publicly known. The fixing element of one embodiment is essentially T-shaped and is fixed to the body part by rivets or screws, or glued or welded in place. A snap lock element is arranged on the securing element, and the gasket profile is secured by a complementary snap lock element mounted thereon. Fixing such fixing elements to body parts is a labor intensive task.

[0010] Based on this situation in the art, the present invention aims to develop a detachable connecting element which, together with the gasket profile, facilitates the mounting and dismounting of components.

[0011]

The above object is achieved not only by the connecting element having the features of claim 1, but also by the detachable mounting structure of the gasket section having the features of claim 7. Advantageous embodiments of the coupling element are set out in dependent claims 2 to 6, and 8 to 10.

At the heart of the invention is the function of various connecting or securing elements to facilitate the mounting and dismounting of individual body parts and components, such as, for example, sheet metal for motor vehicle doors, and their gasket profiles. It consists in being integrated into one single connecting element. For this purpose, in addition to the engagement surface for the assembly tool, the head of the connecting element is provided with at least one further holding element, preferably in the form of a recess, in which the components, preferably gasket profiles, are provided Can be grasped and engaged. The function of screwing the body parts, for example two door sheets together, with the connecting element is achieved by the same components holding the gasket profile.

If the recess is configured as a groove that concentrically surrounds the central longitudinal axis of the connecting element, especially if the recess is arranged at the edge of the head, it is thereby wider for gripping mounting of components. The presence of a support base has proven to be particularly advantageous. This also gives
Components that can be gripped and engaged in only one direction by the head can be gripped and engaged regardless of how far into the head the screw is screwed.

Certain design advantages by providing the screw with a cylindrical head and forming a recess in the outer surface of the head, as well as providing an engaging surface for an assembly tool located in the center of the head. It was revealed that This requirement includes, for example, Allen-head Torx screws.
head type Torx screw).

[0015] The screw according to the invention can be used for the first door of a motor vehicle.
Preferably, it is suitable not only for establishing a detachable connection between the inner sheet metal element and the second inner sheet metal element, but also for subsequently gripping and connecting the gasket profile to the door. For this purpose, the gasket profile presents a snap-in element that can be connected by gripping engagement with the channel recess of the head of the screw. If the gasket profile is fixed by gripping engagement,
The waviness of the gasket profile, which can weaken the sealing effect, can be avoided. Since the profiles can be assembled at a later point in time, the inner sheet metal elements can be assembled without disturbing the gasket profiles. The same is true for decomposition. The gasket profile may also have the function of covering the transition between the two internal sheet metal elements.

In accordance with the present invention, the above-described components have their size, similar to those claimed and described in the embodiments,
Because there are no exceptional conditions with respect to dimensions, materials and technical concepts, selection criteria known to exist in each field of application are freely and freely applicable within the scope of the claims.
